Abstract
In the manufacturing process, such as a metal press or a die cast, it is not easy to repair and/or modify the molds because the molds are made of hard and heat resisting metals. In this study, we proposed a new type of heat resisting paste of inorganic polymer based composites for repairing the metal structures. The matrix of these composites is inorganic adhesives in which many pores are made as curing with water evaporation. Therefore, to improve the strength of such a porous brittle material, low melting metal particles are mixed is cured. Thermal expansion coefficient of the composite was measured from a room temperature to 600 degrees Celsius. Elastic modulus and strength of the composite specimens are also evaluated by the compressive test and bending test.In the manufacturing process, such as a metal press or a die cast, it is not easy to repair and/or modify the molds because the molds are made of hard and heat resisting metals.
